Dunno if this was already mentioned but a customizable deadzone needs to be implemented. My DualShock 2 joypad has a faulty joystick and is causing havick with the mouse when a dialogue is open. I would suggest a slider and a label displaying the currently captured value of the joystick, if the joystick value falls within the deadzone (preferably the left side of the slider) then 0 should display instead, in this way the user can move the slider until they see 0 which in turn means it cannot play havick with the game at any point.
